摘要： Expanded metal sheets are used to produce tubular filters. The expanded metal sheet has a multiplicity of rows of openings arranged to reduce nesting when the sheet is rolled on itself. In particular, the pitch between the rows of openings, the sizes of the openings, or both the pitch between the rows of openings and the sizes of the openings are varied to reduce nesting when the expanded metal sheet is rolled on itself. The filters can include external circumferential grooves, rounded corners produced by a point loading process, textured surfaces between openings, and/or torturous internal paths produced by non-perforated areas of an expanded metal sheet. The expanded metal sheet can be composed of carbon steel coated with a material having a higher heat conductivity, e.g., tin. Among other things, the filters can be used in automobile airbag inflators to capture slag and absorb heat produced by the inflator's explosive charge.

摘要： Expanded metal sheets (5) are used to produce tubular filters (13). The expanded metal sheet (5) has a multiplicity of rows of openings arranged to reduce nesting when the sheet (5) is rolled on itself. In particular, the pitch between the rows of openings, the sizes of the openings, or both the pitch between the rows of openings and the sizes of the openings are varied to reduce nesting when the expanded metal sheet (5) is rolled on itself. The filters (13) can include external circumferential grooves (3), rounded corners (19) produced by a point loading process, textured surfaces (37) between openings, and/or torturous internal paths produced by non-perforated areas of an expanded metal sheet. The expanded metal sheet (5) can be composed of carbon steel coated with a material having a higher heat conductivity, e.g., tin.

摘要翻译：膨胀金属板用于生产管状过滤器。膨胀的金属片具有多个排开口，排列成当片材自身卷绕时减少嵌套。特别地，改变开口行之间的间距，开口的尺寸，或开口行之间的间距和开口尺寸两者之间的间距，以便当膨胀的金属板自身卷绕时减少嵌套。过滤器可以包括外部圆周凹槽，通过点加载过程产生的圆角，开口之间的纹理表面和/或由膨胀金属板的非穿孔区域产生的曲折内部路径。膨胀金属板可以由涂覆有较高导热性的材料的碳钢（例如锡）组成。除其他之外，过滤器可以用于汽车安全气囊充气机中以捕获炉渣并吸收由充气机的炸药产生的热量。
